TIME-CONTROL SWITCH.-

Application Med December 12, 1925. Serial No. 75,068.

This invention relates to time control switches and is an improvement over U. S. Letters Patent #1,411,910 granted me April 4th, 1922.

The principal object of the invention resides in a means for attachment to an alarm clock for actuating a push button electric switch for lighting a lamp or closing a circuit at the same time that the alarm is sounded, so that a person may set the alarm before retiring at night for a predetermined time, and will be automatically provided with light at that particular time. It will be understood that the electric lamp circuit may be tapped to connect an electric heater, cofiee percolator or the like therewith, so that any other household appliance may be simultaneously controlled upon the operation of the switch.

Another object is to provide a time switch operable by a clock-work mechanism, and which may be operated independently of the clockwork mechanism should it be desired to close or open the switch at any time.

A further object of the invention is the provision of an attachment for alarm clocks which may be easily and quickly applied to any well-known type of alarm clock without necessitating radical changes in the construction of the clock.

A further object is to provide a time switch which is simple in construction, inexpensive of manufacture and highly eiiicient in operation.

\Vith these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which I Figure 1 is a rear elevation of an alarm clock with parts broken away and showing my invention mounted thereon.

Figure 2 is a horizontal sectional view on the line 22 of Figure 1.

Figure 3 is a collective perspective view of the several parts which constitute my invention.

Referring more particularly to the drawing, the reference numeral designates an electric lamp base upon which is mounted an alarm clock 11 of the usual well-known construction, and which alarm clock includes a casing 12 having a collar 13 rising therefrom to which is removably connected, an electric switch socket 14 for the reception of an electric lamp 15 or the like. The alarm clock also includes an alarm winding shaft 16 to which a cam 17 is fixedly connected.

The switch socket l i includes an electric switch mechanism operable by a push button or bar 18 which passes transversely therethrough, the ends of the push button projecting beyond the sides of the socket.

My improved switch operating mechanism includes a plate 19 of a shape to conform to the shape of the top of the clock casing and is slotted as at 20 to fit about the collar and to allow the plate to slide with respect to the casing. The plate is also slotted to provide spaced pintles 21 and 22 which serve as pivots for removably supporting the respective levers 23 and 24. The casing 12 of the clock is provided with spaced slots 25 and 26 to allow the lower ends of the levers to extend therein for .a purpose now to be explained. A portion of the material stamped to provide the slot 26 is bent inwardly as at 27.

The lever 23 is in the form of a bell crank lever and has an upper arm 28 and a lower tail 29. The tail 29 carries a lug 30 which is normally disposed in the path of movement of the cam 17, while thefree end of the arm 28 is provided with a head 31 adapted to engage one end of the push button 18 for moving the same to an on position during the operation of the alarm.

The lever 24 comprises a tail 32 which is formed with a tooth 33 for co-action with one end wall of the slot 26 to lock the plate 19 against sliding movement during the actuation of the lever 23 to move the push button to an on position. The inwardly bent portion 27 serves to limit the inward pivotal movement of the lever 24. The lever 24 also has a head 34 on its free end for engagement with the opposite end of the push button, and which head is adapted to be manually pushed to shut-oii the switch.

A contractile spring 35 has one end connected to the plate 19 and its other end to the casing 12 and tends to hold the plate 19 in a position so that the tooth 33 will engage the end wall of the slot 26, and the lever 23 willengage the push button 18.

The spring also permits the plate to temporarily shifted when operating the lever 24 to move the pivot point'of the lever 23 to allow the push button to move to an off position.

A C-shaped washer 36 is interposed between the socket 14 and the casing 12 and is held clamped against the casing by means of the socket. The washer is provided with an offset lug 37 which overlies the plate 19 and serves as a guide for preventing upward movement of the plate during its sliding operation and also lateral movement of the same. i

In operation, weshall presume that the parts are in a position shown in full lines in Figure 1 of the drawing, that is, the switch is off, and it is desired to have the switch turned on at a predetermined time. The a arm clock is of course set in the usual manner to sound the alarm at this particular time. As the alarm is sounded, the winding alarm shaft 16 rotates thus causing the cam 17 to also rotate. The tail of the lever 23 being disposed in the path of movement of the cam will cause the lever to be rocked, thus forcing the head 31 against the push button 18, moving the same to an on position. At the time the lever 23 is in the position as shown in full lines, the lever 24 is away from the push bar and locked by the tooth 33 engaging the wall of the slot 26. The on position of the parts is shown In dotted lines in Figure 1 and should it be desired to manually turn off the switch, the head 3 1 is pushed against the push bar which causes the tooth to disengage and shifts the-plate 19 and simultaneously moves the pivot point of the lever 23 so as to allow the lever to move out of pressing engagement with the push bar. However, should the high face of the cam stop when in engagement with the tail of the lever, the same will in no way affect the movement of the lever 23 to an off position as the pivot or fulcrum point of the lever is moved and is capable of such movement as is necessary to move the head 31 out of the path of the push button. When manual pressure is released from the lever 24, the spring 35 returns the plate and lever 24 to normal position.

From the foregoing description, it will be seen that the lamp will be automatically lighted when the alarm is sounded, and if desired, an attachment plug 38 may be electrically connected with the switch so that various appliances such as an electric heater may be automatically turned on when the switch is closed. The switch can be manually operated without depending upon the an alarm mechanism having a winding sha t, I

a cam fixedly mounted thereon, an electric switch including a slidable actuating bar, and a lever operable by said cam for moving said bar to an on position, a second lever operatively associated with said first lever for moving the latter away from the actuating bar and for moving the former into engagement with said bar to move the bar to an off position.

2. In combination with an electric lamp, an alarm clock-work having a winding shaft, a cam fixedly mounted thereon, an electric switch including a slidable actuating bar, a slidable plate, a pair of levers pivotally mounted upon said plate for engagement with opposite ends of said actuating bar, and co-a'cting means for holding said plate in position to hold one of said levers in the path of movement of said cam for actuation thereby for moving said actuating bar to an on position.

3. In combination with an electric lam an alarm clock-work having a winding sha t, a cam fixedly mounted thereon, an electric switch including a slidable actuating bar, a slidable plate, a pair of levers pivotally mounted upon said plate for engagement with opposite ends of said actuating bar, coacting means for holding said plate in position to hold one of said levers in the path of movement of said cam for actuation thereby for. moving said actuating bar to an on position, and a tension spring for said plate for automatically causing the operation of said co-acting means.

1. In combination with an electric lamp, an alarm clock-work having a winding shaft, a cam fixedly mounted thereon, an electric switch including a slidable actuating bar, a slidable plate, a pair of levers pivotally mounted on said plate for engagement with the respective ends of said actuating bar one of said levers extending into the path of rotation of said cam for actuation thereby, and co-acting means between said other lever and the casing of said alarm clock-Work for holding the plate against sliding movement during the actuation of said other lever by said cam.

In testimony whereof I have afiixed my signature.
